KA4- Stem Cells Flashcards
1
Q
What are the two types of stem cells?
A
Tissue stem cells
Embryonic stem cells
2
Q
What can unspecialised stem cells do?
A
Divide by repeated mitosis, remaining undifferentiated
Differentiate into specialised cells
3
Q
Are embryonic SC pluripotent or multipotent?
A
Pluripotent
4
Q
Are tissue SC pluripotent or multipotent?
A
Multipotent
5
Q
What does multipotent mean?
A
Can only turn into limited cell types
6
Q
What is a blastocyst?
A
Embryonic SC which are found in an early embryo
7
Q
What does pluripotent mean?
A
Can turn into all cell types
8
Q
What do all genes in an embryonic DC have the potential to do?
A
Be switched on
9
Q
Why are tissue SC multipotent?
A
As some genes have already been switched off
10
Q
What are tissue SC used to do?
A
Replace cells in tissue where they are located so growth + repair
